iOS 3.2.2 and Jailbreak
While it has been reported that once you upgrade to iOS 3.2.2 that you can't Jailbreak using jailbreakme.com anymore there hasn't been any confirmation on whether or not the update will wipe out an already jailbroken iPad.
Any first hand info from someone here yet?
Since 3.2.2 is delivered as an entire firmware release, not just a patch, it will absolutely remove your jailbreak, and it will be impossible to re-jailbreak using the PDF exploit at jailbreakme.com.
